I build bmx trails. To make a lot less work, we gotta cut trees up. We also need to keep the noise down, so our solution is a hand saw or electric chain saw. I want to run an electric chainsaw, 12 amps. Keep in mind, We don't have any power supply in the woods.

I would like tok run the inverter (2000w), two extra batteries, and a battery isolator in a bed box.

Has anyone done anything like this before? I've searched but haven't come up with anyone doing extra batteries or isolators
